(a) the room-temperature electrical conductivity of a semiconductor specimen is 13 (ω-m)-1. the hole concentration is known to be 4.0e+20 m-3. the electron and hole mobilities for this material are 0.38 and 0.18 m2/v-s, respectively. compute the electron concentration. (use scientific notation.) m-3
(b) on the basis of the result in part (a), is the specimen intrinsic, n-type extrinsic, or p-type extrinsic? the tolerance is +/-2%
